1 Claim.

The present invention relates to new and useful improvements in feedersforuse primarily for the feeding of processed clays and muds into thedrilling mud used in oil and gas wells, although it will be understoodthat the device may be used for any other purpose for which it may befound adapted and desirable.

The primary object of the invention is to provide, in a manner ashereinafter set forth, a feeder of the aforementioned character which isadapted to be vibrated whereby a steady, uniform flow of the materialwill be had.

Other objects of the invention are to provide a feeder of the characterdescribed which will be comparatively simple in construction, strong,durable, highly efficient and reliable in use, compact and which may bemanufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in side elevation of a material feeder constructed inaccordance with the present invention.

Figure 2 is a top plan view of the device.

Figure 3 is an end elevational view.

Figure 4 is a view in vertical section through the lower portion of thehopper.

Figure 5 is a view in horizontal section, taken substantially on theline 55 of Figure 4.

Figure 6 is a fragmentary view in perspective, showing the looseconnection of the agitator to the frame.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises ametallic stand which is designated generally by reference character I.The stand I includes a pair of spaced supporting legs 2 between whichbraces 3 extend. The stand I further includes an elongated,substantially horizontal frame 4 comprising a pair of spaced, parallelside bars 5 having one end pivotally secured at 6 to the upper endportions of the legs 2 for vertical swinging movement. Spaced crossmembers I extend between the side bars 5 of the frame 4.

Mounted in the frame 4 is a hopper B for the reception of the materialto be fed, said hopper including, on its lower end, a, discharge neck 9.A hand adjusted gate valve l0 controls the neck 9.

As illustrated to advantage in Figure 6 of the drawing, one of the crossmembers 1 of the frame 4 has formed therein an opening I l which loose-1y accommodates one end portion of an agitator rod I2. The agitator I2passes through a live rubber bushing I3 into the lower portion of thehopper 8 and terminates in a downturned end portion which is operable inthe discharge neck 9 and which extends to a point closely adjacent thegate valve If].

It is thought that the operation of the device will be readily apparentfrom a consideration of the foregoing. Briefly, the free end of theframe 4 is connected to any suitable vibrating means. The material to befed is placed in the hopper 8 and the valve I0 is adjusted. As thedevice is vibrated, the frame 4 pivots at 6 on the legs I and thematerial in the hopper 8 is discharged by gravity through the neck 9 andthe valve l0. Shaking of the device in the above-described manner causesthe lower end portion of the agitator l2 to vibrate in the neck 9,thereby positively preventing clogging and insuring a steady, uniformfeed of the material. As hereinbefore stated, the upper end portion ofthe agitator l2 is loose in the opening ll, whereby limited universalswinging movement of said agitator in its resilient mOunting I3 will behad.

It is believed that the many advantages of a material feeder constructedin accordance with the present invention will be readily understood, andalthough a preferred embodiment of the device is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction may be resorted to which will fall within the scope of theinvention as claimed.

What is claimed is:

A material feeder of the character described comprising a substantiallyhorizontal supporting structure pivoted at one end to be swung about ahorizontal axis whereby said structure may be shaken up and down, amaterial receiving hopper on said structure depending therefrom with abottom discharge neck and rigidly connected to said structure, wherebysaid hopperis adapted to be shaken up and down with said structure, aresilient bushing mounted in one side wall of said hopper, an agitatingrod having an upper end loosely connected to said structure and a lowerright angled end extending through said bushing into said hopper anddown into said neck, said bushing forming a cushion support for said rodwhereby, when said hopper is shaken up and,

down, said rod will be vibrated independently of up and down movement ofsaid hopper to cause said lower end thereof to agitate material in saiddischarge neck and thereby prevent clogging of said neck.
